The #$ reader macro will now try to look up foreign variables if it can't find a constant definition.

It appears that Apple isn't going to provide a

The Objective-C bridge works on PPC64 now.

REBUILD-CCL takes an :update keyword argument; when T, it will run svn and try to deal correctly

Updated bundled ASDF.
